SPECIFICATION forming part of Letters Patent No. 757,975, dated April I9, 1904.

Application iile. August 19, 1903.

To all whom it may concern:

Be it known that I, WILLIAM T. SN ELL, a citizen ofthe United States, and a resident of Octave, in the county of Yavapai and Territory of Arizona, have invented new and useful Improvenients in Pipe 'or Bar Cutters, of which the following is a full, clear, and exact description. l

This invention relates to certain novel and useful improvements ina cutting-tool for pipes, tubes, and bars of metal.

In carrying out the present invention I have particularly in view the provision of a cutting sired and essential vfeatures of strength, du-

A furthe!` object of my invention is to profit and securely clamp any size bar or pipe while the cutting operation is being proceeded with, the arrangement of the parts being such that the size and-depth of the cut made bythe tool may be regulated, depending entirely upon the force or pressure exerted through the handle by the operator.

Still another object of my invention is to provide a tool which will cut bar-iron or pipe evenly and quickly, while at the same time the bulging ofthe pipe on the inside, which often occurs in the use of implements now in use will be obviated, and it is unnecessary to ream out the pipe, which operation of reaming is apt to leave burs on the outside.

With the above-recited objects and others of a similar nature in View my invention consists in the construction, combination, andarrangement of parts, as is described in vthis specification, delineated in the accompanying drawings, and set orthin the appended claims.

Reference is to-be had to the accompanying drawings.' forming a part of this specification, in which Vsimilar characters of reference indicate corresponding parts in all the iigures.

Figure 1 is a side view of'a tool embodying shown inv section to illustrate theinterior formation of the same. Fig. 2 is a top side view of my improved tool, showing the manner of employing the same in cutting va pipe or bar; and'Fig. 3 is a transversesectional serial No. 170,014. (no man l view taken through the cutter-block and cutter-block frame on the line 3 3 of Fig. 1.'

Referring now to the accompanying drawings in detail, A designates the main bodyportion or frame of the tool, which is substantially rectangular in shape and is provided with a front jaw portion 5 -in the nature of a hook or curve designed to engage and seat one portion of a pipe or-bar, such as shown at B. The frameo the tool is also' formedA at one side with a member 6, which extends'approximately one-half the distance of the length of thecutter-frame, so that an open spaceis left between the curv'edjaw portion of the tool .and the extension 6.. The rear end member 7 ofthe frame is bored and threaded to permit the passage of the rod 8, carryinga handle 9,

said rod finding bearing in the bored portion.

Zand in the hollow like extension 10, formed integral; with the rear end portion 7 of the gliding within the frame A is a jaw-block Chsaid jaw-block being approximately vrectangular in shape and` is provided with a'hollow' interior portion or chamber 11, into which extends the tubular stud 1 2," said tubular stud 12 being slightly tapered in its bore and is adapted to form a seat for the shank of the cutter D, the head d of the cutter being designed to extendor project a short distancev beyond. the outer end of the inclined central portion '13 of the block C, as the bore or passage-way 14 extends from'the outer end j of the block to the interior chamber l1 thereof. In order to permit the vblock to slide readily and easily within the frame, I have provided such block at its longitudinal edge' portion with guideways 14, which guideways extend over and bearagainst the sides of the frame, as' clearly seen in dotted lines inflig.'4

1 and in full lines in Fig. 2, the construction being such that theblock may slide and yet may be held against .lateral movement ordisplacement. The tool, which is inserted within the tubular socket 12, has its shank 4portion *slightly tapered,` so that it Will tightenitself when in use, and within the chamber formed in the block is a heavy coiled spring 15designed to press or retain the tool and tubular stud against the bar being cut, this spring IOO construction i proved cutter will be readily apparent. -The preventing the tool cutting deeper than is def 'sired, as the amount of cutting isl regulated by the pressure exerted upon the handle.

' From the above description, taken in connection with the accompanying drawings, the

and manner of using my irntool is inserted within the socket of the block,

and the pipe, is engaged by the hooked jaw or end portion'of the device. The blo-ck or sliding Jaw may then be moved along the frame into engagement with the pipe at the opposite side tov that seated in thefcurved end portion of .the end portion 7 of the tool through the handle-rod 8,

Figs. 1 and 3, that the moving jaw or block has aiiat side piece c secured thereto through the medium of the block, carryingl the stud portion 12, is secured to the `main 'portion of lthe block through the medium of similar screws c"x c, the base of the tubular stud passing through the fiat end face o2, so that the end of the rod may -bear against. suc'h stud-base and' force the stud,with its tool, inward against the Vtension of the spring. It will also vbe'noted that the curved end portion or stationary jaw 5 of y the main body portion is provided with an aperture 16, through which the cutter may be passed. to insert it in or remove it from' the socket in the movable jaw. A small hole or bore 17 is made in the block to permit a pin or the like to be inserted for starting the tool from the socket. l

The many advantages incident to my im-v proved implement will be readily apparent,

andit is-unnecessaryto dwell upon the same here in detail.

While .1 haveshown and herein described one partieular'embodiment of my invention, it is of course to be understood that I do not limit myself to the precise details of construetion shown herein, as there may be modilica- 'tions and variations in certain respects without departing from the essential features of the movablel of screwsc' e', while the end b2' the invention orsacrificing any of the advantages thereof.

Having thus described my invention, I claim 1. A device of the class described, compris-y ing a main body portion including a stationary Jaw at one end thereof, a'gmovable jaw as new and desire to secure by Letters Patenti slidable on the main body portionrelative to the stationary jaw, said movable jaw having a' hollow interior portion, a movable tubular socket within the hollow portionof the movable jaw, a vtension-spring coiled around the socket and a cutter carried by 'sa-id socket, substantially as set forth.

2. The combination with the main body portion, including a stationary jaw, of a movable jaw slidable on 'the main body portion but -held against lateralmovement, saidmovable jaw having a hollow interior portion, a tubular socket extending into the hllmmnterior portion, a eutter'seated in said tubii'lar socket and having its cutting edge extending through a bore in the movable jaw, and a handlevhaving a rod portion threadedv in the main body vportion and designed to bear against the movable jaw 'for moving it toward'the stationary jaw, the construction being such that a pipe or bar may be clamped between the movable jaw and the stationary jaw and cut with the edge of the cutter, substantially as set forth.

3. The combination of a'main body portion, including a statiolfary jaw, a movable jaw having a hollow interior portion slidable on the main body portion toward and from the stationary jaw, said movable jaw being prol vided with guideways' to engage with the sides of the main body portion and prevent lateral movement of the movable jaw, atu bularsocket extending into the interior portion of the movable jaw, a cutter carried by said socket, a tension-spring coiled about the socket and loccupying the hollow interior portion of the movable jaw, and a handle having a threaded rod portion designed to bear against the movable jaw for moving it relative to the stationary jaw, substantially asset forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
